Abstract Among the prospective non conventional boat
building materials, rubber wood has gained acceptance
for being an easily available agricultural byproduct.
It is highly vulnerable to biodeterioration.
The service life of rubber wood under estuarine
conditions is estimated to be about six months.
Present investigation is focused on the assessment
of extent of protection imparted to rubber wood by
preservatives like Chromated Copper Arsenate
(CCA), dual preservative and physical barriers like
paint and Fibreglass Reinforced Plastic (FRP).
Eighteen months study showed that untreated
rubber wood failed to prevent marine borer attack
in six months of exposure to estuarine waters.
Among the three retentions of CCA studied, 16 and
29 kg m-3 showed susceptibility to attack by
Sphaeroma spp. and Teredo spp. on prolonged
exposure. Higher retention of CCA viz., 42 kg m-3
and dual treatment imparted higher degree of
protection to rubber wood. Physical barriers that
were applied on CCA treated panels accorded a
100% protection to rubber wood. Commercially
available CCA treated marine grade plywood
samples showed moderate attack in twelve months
of exposure and failed after eighteen months.
